SLX1A

Chr 16

structure-specific endonuclease subunit SLX1A

Also known as: GIYD1

The SLX1A protein serves as the catalytic subunit of the SLX1-SLX4 structure-specific endonuclease that resolves DNA secondary structures during DNA repair and recombination by cleaving branched DNA substrates and Holliday junctions. Pathogenic variants in SLX1A cause autosomal recessive microcephaly, growth retardation, and retinal degeneration. This gene shows tolerance to loss-of-function variants with relatively low constraint scores.
